PHACELIA FAMILY 267 



K. Brandegee; Limekiln Creek, Monterey coast, Jepson 1675; Pacific Grove, Seller 6716). At 

 Monterey it passes into the ordinary form of P. malvaefolia. 



Tax. note. — In the seeds of Phacelia malvaefolia the pits are rather large and shallow, the 

 intervening ridges %vithout projecting points. In the seeds of var. loasaefolia the pits are smaller 

 and deeper, the ridges with projecting points. Note, however, Espinosa Canon, Monterey Co., 

 Hoover 4116, the seeds intermediate as to pitting and sometimes 4 in a capsule, sometimes 6, or in 

 some capsules one cell contains 2 large seeds, the other 3 smaller seeds. — E. F. Hoover.

32. p. rattanii Gray. Stem branching from the base, % to l^/^ feet high; 

 herbage thinly but conspicuously spreading-bristly ; leaf -blades ovate in outline, 

 truncatisli or subcordate at base, thin, % to 2 inches long, shallowly pinnate-lobed, 

 the lobes irregularly serrate; racemes slender, loose or somewhat dense, % to 2 

 inches long, terminal in Is or 2s on the stems and branches or borne on peduncles 

 in the upper axils; four calyx-lobes spatulate, one obovate and slightly longer; 

 corolla dull-white or bluish-white, funnelform, 2 to 2i/2 lines long ; scales very nar- 

 row and very long, wholly adnate, almost equaling the filaments in length ; stamens 

 included; filaments hairy; style cleft nearly %. 



Brushy hillslopes, 1000 to 4000 feet : Coast Ranges from Santa Clara Co. to 

 western Siskiyou Co. ; Sierra Nevada in Shasta Co. North to southern Oregon. 



June-July. 



Field note. — In aspect and in herbage Phacelia rattanii closely resembles P. malvaefolia. 

 Although not a rare plant it is somewhat obscure and is probably more frequent than collections 

 suggest. The bristly hairs are somewhat stinging.
